Given a freshly produced quantreg.Rcheck directory, I was able to reproduce this crash by running R -d gdb # make

Gurus: I have a new version of my quantreg package with minimal changes, mainly to fix some obscure fortran problems. It fails R CMD check ?as-cran with the error: Running examples in ?quantreg-Ex.R? failed The error most likely occurred in: > base::assign(".ptime", proc.time(), pos = "CheckExEnv") > ### Name: plot.rqss > ### Title: Plot Method for rqss Objects

Hi, I often find myself staring at IR and wanting to look at the C source code it corresponds to. To do so, I look up the debug identifier for the given IR line, scroll to the bottom of the IR file to find the debug identifier, look at the debug location (source and column), and then look at the source file. Too many steps. What would be great is a tool that took two files, i.e., a .c file and a

...tions in the function will need to > use them (though different metadata arguments may be used in different > scopes). So I think that opens our options a bit. If the pragma applies to the entire function then would it be as simple as a pass to convert intrinsic calls into whatstheterm SNodes (?) after the optimization passes have run? Meaning, we can bypass any changes to the AST? That would still leave the backend changes to be done, of course. BTW, I thought that optimization passes were allowed to drop metadata. So what happens to the metadata on the constrained intrinsic calls? O...

This patch modifies the physinfo hcall to export NUMA CPU and Memory topology information. The new physinfo hcall is integrated into libxc and xend (xm info specifically). Included in this patch is a minor tweak to xm-test''s xm info testcase. The new fields in xm info are: nr_nodes : 4 mem_chunks : node0:0x0000000000000000-0x0000000190000000

I get an error in the hpricot-gem on Windows XP sp3. I have tested different versions of it and combined them with different versions of sequel (including the latest of both). The error triggers on the line when I do: require ’hpricot’. The line that causes the error in the hpricot-gem in the file elements.rb (line 395) looks like this: nth = proc { |num,i| self.position == num.to_i } What is

(Second try to send this. I wonder if the first one gotten eaten by a spam filter; I'll link to patches instead of attaching them.) Here are the tincctl patches I've been working on. They apply to http://www.tinc-vpn.org/svn/tinc/branches/1.1@1545. I intend to commit them once the crypto stuff's fixed. Since they're basically done, I'm emailing them now for review and in case
